The glutathione contents in whole blood of 53 normal Chinese males, 52 normal Chinese females and 31 patients with gynecological cancer were determined by iodometric titration. Total glutathione levels in the whole blood of these three groups were 41.5 ± 0.74, 38.3±0.74 and 32.6±1.20 mg% respectively. A significant difference existed between the values of total glutathione in normal male and female adults; however, the contents of reduced or oxidized glutathione showed no difference. The reduced and total glutathione...

The glutathione contents in whole blood of 53 normal Chinese males, 52 normal Chinese females and 31 patients with gynecological cancer were determined by iodometric titration. Total glutathione levels in the whole blood of these three groups were 41.5 ± 0.74, 38.3±0.74 and 32.6±1.20 mg% respectively. A significant difference existed between the values of total glutathione in normal male and female adults; however, the contents of reduced or oxidized glutathione showed no difference. The reduced and total glutathione levels in the whole blood of patients with gynecological cancer were found to be lower than that of the normal; while their oxzidized glutathione levels showed a prominent increase. There was a significant positive correlatoin between the RBC counts and total glutathione levels in patients with gynecological cancer, but not the other two groups of normal subjects.Oxygen capacity in the whole blood of 46 normal Chinese males, 47 normal Chinese females and 31 patients with gynecological cancer was estimated by Scholader-rougton's miorogasometry, being 19.2 ± 0.25, 16.8 ±0.26 and 12.8 ± 0.61 ml% respectively. The difference between the values of normal male and female adults and that between those of the patients and normal females were very significant.The possible mechanism of these biochemical changes is briefly discussed.

本文著者用碘量滴定法初步观测了53名和52名我国正常男、女成人及31例妇科癌肿患者的全血谷胱甘肽含量。三组的全血谷胱甘肽总量分别为41.5±0.74,38.3±0.74和32.6±1.20毫克%。男、女成人的该测定值相差显著,但他们的全血氧化型或还原型谷胱甘肽含量则否。与正常女性组比较,妇科癌肿患者的全血谷胱甘肤总量及其还原型含量均呈明显降低,而氧化型谷胱甘肽则明显升高。正常人组的红细胞计数和全血谷胱甘肽总量无明显相关,而妇科癌肿患者则有极显著的正相关。另外,还用Scholander与Roughton 微量分析法观测了46名和47名我国正常男、女成人及31例妇科癌肿患者的全血氧容量,三组结果分别为19.2±0.25,16.8±0.26和12.8±0.61毫升%;发现正常男女之间以及妇科癌肿患者与正常女性之间均有明显差异。 对上述变化的可能机制,作了一些初步讨论。

The method (LS 76——82) of the Ministry of Commerce China, the method of Food Hygiene Iaws and Regulations of Japan and Acetic acid glacial-chloroform direct abstraction method were used to abstract fats and oils in fried instant noodle. Iodometric method was used to determine peroxide values. There methods were compared. The results indicated that the differences of the valuse were siginficant with the different methods. The values obtained by the standard method of China were lowest and the standard deviation was lowest. The values determined were highest with the method of Japan. The values were medium by acetic acid glacial-chloroform and were close to the standard method of the country. The two latter methods were similar in deviation.

本实验选用我国商业部部颁标准法)L S76-82),"日本食品卫生法规"规定法及氯仿——冰醋酸混合液直接提取法等三种方法从油炸方便面中提取油脂,以碘量滴定法测定过氧化值,对测定值进行了比较.结果表明,不同方法制备的试样测定值差异极为显著.我国部颁标准法制备的试样测定值最低,标准偏差也最小.日本规定法制备的试样测定值最高.直接提取法居中,与我国部颁标准法较为接近.后两种方法的标准偏差近似.

X-ray photoelectron spectrometry and iodometric titration techniques have been used to analyze YBa_2Cu_3O_(~7)(YBCO)superconductor and related compounds.The results of XPS analysis for YBCO superconductor and NaCuO_2 show that Cu~(3+) is not present in YBCO supsrconduetor.The results of iodometric titration show that all the high-T_5 super- conducting YBCO and related Ba-containing compounds annealed at 600℃ contain the“two- -electron oxidant”,whereas no“two-electron oxidant”can be determined in the Ba-free...

X-ray photoelectron spectrometry and iodometric titration techniques have been used to analyze YBa_2Cu_3O_(~7)(YBCO)superconductor and related compounds.The results of XPS analysis for YBCO superconductor and NaCuO_2 show that Cu~(3+) is not present in YBCO supsrconduetor.The results of iodometric titration show that all the high-T_5 super- conducting YBCO and related Ba-containing compounds annealed at 600℃ contain the“two- -electron oxidant”,whereas no“two-electron oxidant”can be determined in the Ba-free compound and YBCO compounds quenched by liquid nitrogen.Above results imply that the “two-electron oxidant”in iodometric titration of YBCO superconductor is not Cu~(3+)ion,but probably peroxide-like oxygen species.

用 XPS 法和碘量法分析了 YBCO 超导体及有关化合物。结果表明 YBCO 超导体碘量滴定反应中的“两电子氧化剂”不是 Cu~(3+)离子,而可能是O_2~(2-)(或 O~(1-))种类的氧离子。
